Summary of the Invention

Problems to be Solved by the Invention

[0004] A connector lock device for locking the connection between a charging connector of charging equipment and an inlet of a vehicle may be provided in the charging equipment. When external charging is completed, the charging equipment equipped with the connector lock device releases the connection between the charging connector and the inlet. As a result, the user can remove the charging connector from the inlet.

[0005] Here, when the user leaves the vehicle during external charging, it is common for the user to lock the door. When the user returns to the vehicle and external charging has been completed, the user removes the charging connector from the inlet and closes the lid.

[0006] However, for example, like the vehicle disclosed in Patent Document 1, when the lid lock device is locked in conjunction with the door lock device, even if the user tries to close the lid, the lid cannot be closed because the lid lock device is in the locked state. In order to unlock the lid lock device, the door must be unlocked, and there is room for improvement from the perspective of user convenience.

[0007] The present disclosure has been made to solve the above problems, and an object of the present disclosure is to improve user convenience in external charging using a charging facility equipped with a connector lock device.

Means for Solving the Problems

[0008] A vehicle according to an aspect of the present disclosure is configured to be capable of performing a first external charging for charging an in-vehicle power storage device using electric power supplied by a first charging facility provided outside the vehicle. The vehicle includes a first power receiving port configured to be connectable to a first connector of the first charging facility, a first lid provided at the first power receiving port, a first lid lock device configured to switch the first lid between a locked state and an unlocked state, and a control device configured to control the first lid lock device to be in the locked state or the unlocked state. When the vehicle's entry / exit door is locked, the control device, when the first lid is closed, interlocks with the locking of the entry / exit door to put the first lid lock device in the locked state, and when the first lid is open, keeps the first lid lock device in the unlocked state until the first external charging is started, puts the first lid lock device in the locked state when the first external charging is started, and puts the first lid lock device in the unlocked state when the first external charging is completed.

[0009] According to the above configuration, even when the boarding and alighting door of the vehicle is locked, when the first lid is open, the control device does not interlock the first lid locking device with the locking of the boarding and alighting door. The control device keeps the first lid locking device in the unlocked state until the first external charging is started, so that the user can close the first lid even at this stage. Then, when the first external charging is started, the control device locks the first lid locking device, and when the first external charging is completed, the control device unlocks the first lid locking device. Since the first lid locking device is unlocked when the first external charging is completed, the user who has removed the first connector from the first power receiving port can close the first lid without any operation. Therefore, the convenience of the user can be improved.

[0010] In an embodiment, the first charging facility includes a first connector locking device configured to switch the connection between the first connector and the first power receiving port between a locked state and an unlocked state. When the first external charging is executed, the connection between the first connector and the first power receiving port is locked by the first connector locking device, and when the first external charging is completed, the connection between the first connector and the first power receiving port is unlocked by the first connector locking device.

[0011] According to the above configuration, the first connector locking device that switches the connection between the first connector and the first power receiving port between a locked state and an unlocked state is provided in the first charging facility. And when the first external charging is completed, the connection between the first connector and the first power receiving port of the first power receiving port is unlocked. Thereby, the user can remove the first connector from the first power receiving port without any operation after the first external charging is completed.

[0012] In an embodiment, the vehicle further includes a relay that switches the supply and cut-off of operating power to the first lid locking device. The control device controls the first lid locking device to be in a locked state or an unlocked state by controlling the relay.

[0013] According to the above configuration, the control device can control the first lid locking device by controlling the relay.

[0014] In one embodiment, the vehicle is further configured to perform a second external charging for charging the power storage device using the power supplied by a second charging facility provided outside the vehicle. The vehicle further includes a second power receiving port configured to be connectable to a second connector of the second charging facility, a second lid provided at the second power receiving port, a second lid locking device configured to switch the second lid between a locked state and an unlocked state, and a second connector locking device configured to switch the connection between the second connector and the second power receiving port between a locked state and an unlocked state. The second lid locking device and the second connector locking device are configured to receive operating power through a relay.

[0015] According to the above configuration, the second lid locking device and the second connector locking device receive operating power through a relay, similar to the first lid locking device. Since it is not necessary to provide a relay for each locking device individually, a circuit for operating each locking device can be configured at low cost. In addition, since the relays for operating each locking device are shared, for example, when the first external charging is started, the second lid locking device also enters the locked state. Thereby, it is possible to suppress pranks on the second lid and the second power receiving port during the execution of the first external charging.

[0016] In one embodiment, the first external charging is DC charging and the second external charging is AC charging.

Advantages of the Invention

[0017] According to the present disclosure, in external charging using a charging facility provided with a connector locking device, the convenience for the user can be improved.

[0019] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. In the drawings, the same or corresponding parts are denoted by the same reference numerals, and the description thereof will not be repeated.

[0020] <Configuration of Vehicle> FIG. 1 is a diagram schematically showing an overall configuration example of a vehicle 1 according to an embodiment of the present disclosure. Referring to FIG. 1, the vehicle 1 includes a power storage device 10, a system main relay (SMR) 15, a power control unit (PCU) 20, a drive device 25, and drive wheels 30. The vehicle 1 is an electric vehicle that drives the drive wheels 30 by the drive device 25 using the electric power stored in the power storage device 10. The vehicle 1 is configured to be capable of AC charging for charging the power storage device 10 using AC power supplied from an AC charging facility 200 outside the vehicle 1, and DC charging for charging the power storage device 10 using DC power supplied from a DC charging facility 300 outside the vehicle 1. Note that the vehicle 1 may be, for example, a plug-in hybrid vehicle further equipped with an engine, or a fuel cell vehicle further equipped with a fuel cell as a power source in addition to the power storage device 10.

[0021] The power storage device 10 is a rechargeable power storage element. The power storage device 10 includes, for example, a secondary battery such as a lithium-ion battery or a nickel-metal hydride battery, or a power storage element such as an electric double layer capacitor. Note that a lithium-ion secondary battery is a secondary battery that uses lithium as a charge carrier, and may include not only a general lithium-ion secondary battery with a liquid electrolyte, but also a so-called all-solid-state battery that uses a solid electrolyte.

[0022] SMR15 is a relay provided between the power storage device 10 and the power line L1 for electrically connecting / disconnecting the power storage device 10 and the power line L1.

[0023] PCU20 is a general representation of a power conversion device for receiving power from the power storage device 10 and driving the drive device 25. PCU20 includes, for example, an inverter for driving a motor included in the drive device 25, and a converter for boosting the power output from the power storage device 10.

[0024] The drive device 25 is a general representation of a device for driving the drive wheels 30. The drive device 25 includes, for example, a motor or an engine for driving the drive wheels 30. Further, the drive device 25 generates electricity when the vehicle brakes or the like by a motor that drives the drive wheels 30, and outputs the generated power to the PCU20.

[0025] As a configuration for performing AC charging, the vehicle 1 further includes a power reception port unit 40, an AC lid 42, a charger 50, and a charging relay 55. The power reception port unit 40 is configured by forming a recess on the outer surface of the vehicle, similar to a conventional fuel filler port. The power reception port unit 40 is provided with an AC inlet 41 (Fig. 2) to which a connector 220 of a charging cable 210 connected to the AC charging facility 200 can be attached. The AC lid 42 is a lid of the power reception port unit 40 and is provided to be openable and closable with respect to the power reception port unit 40 by a joint such as a hinge.

[0026] From the power receiving port unit 40, a connector connection signal P1 indicating the connection state between the AC inlet 41 and the connector 220 of the charging cable 210 is output to a charging ECU (Electronic Control Unit) 60 (described later). The connector connection signal P1 is activated, for example, when the connector 220 is connected to the AC inlet 41.

[0027] The power receiving port unit 40 is provided with a lid switch 81 for detecting the open / closed state of the AC lid 42. The lid switch 81 outputs a lid signal K1 indicating the open / closed state of the AC lid 42 to the charging ECU 60. The lid signal K1 is activated, for example, when the AC lid 42 is closed.

[0028] In addition, the power receiving port unit 40 is further provided with a lid locking device 82 and a connector locking device 83. The lid locking device 82 is configured to switch the closed AC lid 42 between a locked state and an unlocked state. The connector locking device 83 is configured to switch the connection between the connector 220 of the charging cable 210 and the AC inlet 41 between a locked state and an unlocked state. The configurations of the power receiving port unit 40, the lid locking device 82, and the connector locking device 83 will be described in detail later.

[0029] The charger 50 converts and outputs the AC power supplied from the AC charging facility 200 to the voltage level of the power storage device 10 in a state where the connector 220 of the AC charging facility 200 is connected to the AC inlet 41 of the power receiving port unit 40. The charger 50 is configured to include, for example, a PFC (Power Factor Correction) circuit, an inverter, an isolation transformer, a rectifier circuit, etc. The charging relay 55 is a relay for electrically connecting / disconnecting the charger 50 and the power line L2 connected to the power line L1.

[0030] As a configuration for performing DC charging, the vehicle 1 further includes a power receiving port unit 45, a DC lid 47, and a charging relay 57. The power receiving port unit 45 is configured by forming a recess on the outer surface of the vehicle, similar to a conventional fuel filler port. The power receiving port unit 45 has a configuration compliant with the charging standards of CHAdeMO (registered trademark) or GB / T. The power receiving port unit 45 is provided with a DC inlet 46 (Fig. 3) to which the connector 320 of the charging cable 310 connected to the DC charging facility 300 can be attached. The DC lid 47 is a lid of the power receiving port unit 45 and is provided to be openable and closable with respect to the power receiving port unit 45 by a joint such as a hinge.

[0031] From the power receiving port unit 45, a connector connection signal P2 indicating the connection state between the DC inlet 46 and the connector 320 of the charging cable 310 is output to the charging ECU 60 (described later). The connector connection signal P2 is activated, for example, when the connector 320 is connected to the DC inlet 46.

[0032] The power receiving port unit 45 is provided with a lid switch 86 for detecting the open / closed state of the DC lid 47. The lid switch 86 outputs a lid signal K2 indicating the open / closed state of the DC lid 47 to the charging ECU 60. The lid signal K2 is activated, for example, when the DC lid 42 is closed.

[0033] In addition, the power receiving port unit 45 is further provided with a lid locking device 87. The lid locking device 87 is configured to switch the closed DC lid 47 between a locked state and an unlocked state. The configurations of the power receiving port unit 45 and the lid locking device 87 will be described in detail later.

[0034] The DC charging facility 300 according to the present embodiment complies with the charging standards of CHAdeMO or GB / T. Therefore, a connector locking device for switching the connection between the connector 320 and the DC inlet 46 between a locked state and an unlocked state is provided in the DC charging facility 300. Therefore, the power receiving port unit 45 according to the present embodiment does not include a connector locking device.

[0035] The vehicle 1 further includes a charging ECU 60, a body ECU 65, an authentication ECU 70, a door lock device 80, lock relays 100 and 101, and unlock relays 102 and 103. The lock relay 100 and the unlock relay 102 are housed in, for example, a relay box 150. The lock relay 101 and the unlock relay 103 are housed in, for example, a relay box 160.

[0036] Each of the charging ECU 60, the body ECU 65, and the authentication ECU 70 includes a CPU (Central Processing Unit), a memory (RAM (Random Access Memory) and ROM (Read Only Memory)), and an I / F device for inputting and outputting various signals (none of which are shown). The CPU expands and executes the program stored in the ROM in the RAM. The program stored in the ROM describes the processes executed by the CPU. The charging ECU 60, the body ECU 65, and the authentication ECU 70 are connected through an in-vehicle network such as CAN (Controller Area Network) and can exchange information with each other.

[0037] In this embodiment, an example in which the control unit is configured to be divided into the charging ECU 60, the body ECU 65, and the authentication ECU 70 will be described. However, any two or all of the charging ECU 60, the body ECU 65, and the authentication ECU 70 may be configured as one ECU.

[0038] The charging ECU 60 receives, from the power receiving port section 40, a connector connection signal P1 indicating the connection state between the connector 220 of the AC charging facility 200 and the AC inlet 41. Also, the charging ECU 60 receives, from the lid switch 81, a lid signal K1 indicating the open / closed state of the AC lid 42. Further, the charging ECU 60 receives, from the power receiving port section 45, a connector connection signal P2 indicating the connection state between the connector 320 of the DC charging facility 300 and the DC inlet 46. Additionally, the charging ECU 60 receives, from the lid switch 86, a lid signal K2 indicating the open / closed state of the DC lid 47.

[0039] Furthermore, when the connector 220 of the AC charging facility 200 is connected to the AC inlet 41 and a predetermined preparation process for performing AC charging is completed, the charging ECU 60 turns on the charging relay 55. Then, the charging ECU 60 executes a predetermined arithmetic process based on signals from various sensors and information stored in the memory, and performs AC charging by controlling the charger 50 based on the arithmetic result. Also, when the connector 320 of the DC charging facility 300 is connected to the DC inlet 46 and a predetermined preparation process for performing DC charging is completed, the charging ECU 60 turns on the charging relay 57. Thereby, DC charging is executed.

[0040] The verification ECU 70 performs control to permit locking (locking) and unlocking (unlocking) of the boarding door (not shown) by the door lock device 80 by performing wireless communication with the portable device 90 held by the user. Specifically, when the verification ECU 70 detects a door lock operation by the user while the vehicle 1 is stopped, it performs ID verification of the portable device 90. Note that the door lock operation is, for example, an act of the user operating a door lock switch provided on the portable device 90 or touching a door lock sensor provided on the door handle.

[0041] When ID verification of the portable device 90 is successful, the verification ECU 70 outputs a door lock command to the body ECU 65. The verification ECU 70 also performs ID verification of the portable device 90 when detecting a door unlock operation by the user, and outputs a door unlock command to the body ECU 65 when ID verification is successful.

[0042] The body ECU 65 controls the door lock device 80 based on a door lock command or a door unlock command received from the verification ECU 70. The door lock device 80 is configured to switch the entry / exit door from a closed state between a locked state and an unlocked state. The door lock device 80 is provided with a lock relay 100 and an unlock relay 102. The lock relay 100 is a relay that switches between supplying and cutting off operating power for operating the door lock device 80 so as to lock the entry / exit door. The unlock relay 102 is a relay that switches between supplying and cutting off operating power for operating the door lock device 80 so as to unlock the entry / exit door.

[0043] When the body ECU 65 receives a door lock command from the verification ECU 70, it turns on the lock relay 100. This activates the door lock device 80 and the entry / exit door is locked. When the body ECU 65 receives a door unlock command from the verification ECU 70, it turns on the unlock relay 102. This activates the door lock device 80 and the entry / exit door is unlocked.

[0044] As will be described in detail later, the lid lock device 82, the connector lock device 83, and the lid lock device 87 are provided with a common lock relay 101 and an unlock relay 103. In other words, the lid lock device 82, the connector lock device 83, and the lid lock device 87 are configured to operate in conjunction with each other.

[0045] The lock relay 101 is a relay that switches the supply and cutoff of operating power for operating the lid lock device 82 to lock the AC lid 42, operating power for operating the connector lock device 83 to lock the connection between the AC inlet 41 and the connector 220, and operating power for operating the lid lock device 87 to lock the DC lid 47. The unlock relay 103 is a relay that switches the supply and cutoff of operating power for operating the lid lock device 82 to unlock the AC lid 42, operating power for operating the connector lock device 83 to unlock the connection between the AC inlet 41 and the connector 220, and operating power for operating the lid lock device 87 to unlock the lid 47.

[0046] Figure 2 is a diagram showing a configuration example of the power receiving port unit 40 shown in Figure 1. Referring to Figure 2, the power receiving port unit 40 is provided with an AC inlet 41, a lid switch 81, a lid lock device 82, and a connector lock device 83.

[0047] The AC inlet 41 is configured to be able to connect the connector 220 of the charging cable 210. When the connector 220 is connected to the AC inlet 41, the connector connection signal P1 output to the charging ECU 60 is activated.

[0048] The lid switch 81 is configured to be able to detect the opening and closing of the AC lid 42. When the lid switch 81 is pressed due to the closing of the AC lid 42, the lid signal K1 output to the charging ECU 60 is activated.

[0049] The lid lock device 82 includes, for example, a lock pin 82a that can move forward and backward, and a drive device 82b that drives the lock pin 82a. The lid lock device 82 enters a locked state in which the AC lid 42 cannot be opened by moving the lock pin 82a forward from the unlocked position. The lid lock device 82 enters an unlocked state in which the AC lid 42 can be opened by moving the lock pin 82a backward from the locked position. The lid lock device 82 can operate regardless of the open / closed state of the AC lid 42 and can also operate when the AC lid 42 is open.

[0050] The connector lock device 83 is provided near the outer periphery of the AC inlet 41 and includes, for example, a lock pin 83a that can move forward and backward, and a drive device 83b that drives the lock pin 83a. The connector lock device 83 enters a locked state in which the connector 220 of the charging cable 210 connected to the AC inlet 41 cannot be removed from the AC inlet 41 by moving the lock pin 83a forward from the unlocked position. The connector lock device 83 enters an unlocked state in which the connector 220 can be removed from the AC inlet 41 by moving the lock pin 83a backward from the locked position. The connector lock device 83 can operate regardless of whether the connector 220 is connected to the AC inlet 41 or not, and can also operate when the connector 220 is not connected to the AC inlet 41.

[0051] FIG. 3 is a diagram showing a configuration example of the power receiving port unit 45 shown in FIG. 1. Referring to FIG. 3, the power receiving port unit 45 is provided with a DC inlet 46, a lid switch 86, and a lid lock device 87.

[0052] The DC inlet 46 is configured to be able to connect the connector 320 of the charging cable 310. When the connector 320 is connected to the DC inlet 46, the connector connection signal P2 output to the charging ECU 60 is activated.

[0053] The lid switch 86 is configured to be able to detect the opening and closing of the DC lid 47. When the lid switch 86 is pressed due to the closing of the DC lid 47, the lid signal K2 output to the charging ECU 60 is activated.

[0054] The lid lock device 87 includes, for example, a lock pin 87a that can move forward and backward, and a drive device 87b that drives the lock pin 87a. The lid lock device 87 enters a locked state in which the DC lid 47 cannot be opened by moving the lock pin 87a forward from the unlocked position. The lid lock device 87 enters an unlocked state in which the DC lid 47 can be opened by moving the lock pin 87a backward from the locked position. The lid lock device 87 can operate regardless of the open / closed state of the DC lid 47 and can also operate when the DC lid 47 is open.

[0055] FIG. 4 is a diagram showing a configuration example of a circuit for operating the lid lock device 82, the connector lock device 83, and the lid lock device 87. In the vehicle 1 according to the present embodiment, the lid lock device 82, the connector lock device 83, and the lid lock device 87 are connected to a common relay box 160 and receive operating power through the relay box 160.

[0056] Referring to FIG. 4, the lock relay 101 includes a contact 101a and a coil 101b. The contact 101a operates to connect the electric wire L4 to the power supply node 510 when the coil 101b is excited. The contact 101a operates to connect the electric wire L4 to the body ground 520 when the coil 101b is de-excited. The coil 101b is connected to the body ECU 65 through the signal line S1, and the excitation / de-excitation is switched by the body ECU 65. Hereinafter, the state in which the electric wire L4 is connected to the power supply node 510 will be referred to as the lock relay 101 being ON, and the state in which the electric wire L4 is connected to the body ground 520 will be referred to as the lock relay 101 being OFF.

[0057] The unlock relay 103 includes a contact 103a and a coil 103b. The contact 103a operates to connect the wire L5 to the power supply node 510 when the coil 103b is excited. The contact 103a operates to connect the wire L5 to the body ground 520 when the coil 103b becomes non-excited. The coil 103b is connected to the body ECU 65 through the signal line S2 and is switched between excitation and non-excitation by the body ECU 65. Hereinafter, the state in which the wire L5 is connected to the power supply node 510 is referred to as the unlock relay 103 being ON, and the state in which the wire L5 is connected to the body ground 520 is referred to as the unlock relay 103 being OFF.

[0058] Each of the lid lock device 82, the connector lock device 83, and the lid lock device 87 is connected in parallel to each other between the wire L4 and the wire L5.

[0059] As described above, the lid lock device 82 includes a lock pin 82a and a drive device 82b. The drive device 82b includes, for example, a motor and is connected between the wire L4 and the wire L5. The motor included in the drive device 82b rotates forward when a current (lock current) flows from the wire L4 through the motor to the wire L5, and rotates backward when a current (unlock current) flows from the wire L5 through the motor to the wire L4. The drive device 82b advances the lock pin 82a when the motor rotates forward, shifting the lid lock device 82 from the unlock state to the lock state. The drive device 82b retracts the lock pin 82a when the motor rotates backward, shifting the lid lock device 82 from the lock state to the unlock state.

[0060] As described above, the connector locking device 83 includes a lock pin 83a and a drive device 83b. The drive device 83b includes, for example, a motor and is connected between the electric wire L4 and the electric wire L5. The motor included in the drive device 83b rotates forward when a current (lock current) flows from the electric wire L4 through the motor to the electric wire L5, and rotates backward when a current (unlock current) flows from the electric wire L5 through the motor to the electric wire L4. When the motor rotates forward, the drive device 83b advances the lock pin 83a to shift the connector locking device 83 from the unlocked state to the locked state. When the motor rotates backward, the drive device 83b retracts the lock pin 83a to shift the connector locking device 83 from the locked state to the unlocked state.

[0061] The connector locking device 83 may further include a lock detection switch 83c that detects the transition of the connector locking device 83 to the locked state. The lock detection switch 83c is connected to the body ECU 65 through a signal line S3. The lock detection switch 83c is turned ON, for example, when pressed by the lock pin 83a that has moved to the locked position. The lock detection switch 83c is turned OFF, for example, when the lock pin 83a moves from the locked position to the unlocked position and is no longer pressed by the lock pin 83a. The body ECU 65 detects the state of the connector locking device 83 based on, for example, the voltage level of the signal line S3.

[0062] As described above, the lid locking device 87 includes a lock pin 87a and a drive device 87b. The drive device 87b includes, for example, a motor and is connected between the electric wire L4 and the electric wire L5. The motor included in the drive device 87b rotates forward when a current (lock current) flows from the electric wire L4 through the motor to the electric wire L5, and rotates backward when a current (unlock current) flows from the electric wire L5 through the motor to the electric wire L4. When the motor rotates forward, the drive device 87b advances the lock pin 87a to shift the lid locking device 87 from the unlocked state to the locked state. When the motor rotates backward, the drive device 87b retracts the lock pin 87a to shift the lid locking device 87 from the locked state to the unlocked state.

[0063] In the vehicle 1 according to this embodiment, regarding the locking operation, the lid lock device 82, the connector lock device 83, and the lid lock device 87 receive operating power through a common lock relay 101. Also, regarding the unlocking operation, the lid lock device 82, the connector lock device 83, and the lid lock device 87 receive operating power through a common unlock relay 103.

[0064] <Interlocking / Non-interlocking with Door Lock Command / Door Unlock Command> In the vehicle 1 according to this embodiment, the body ECU 65 determines whether to interlock the control of the door lock command and the door unlock command with the relay box 160 based on the open / closed state of the DC lid 47. The body ECU 65 detects the open / closed state of the DC lid 47 based on the lid signal K2 received via the charging ECU 60.

[0065] When the DC lid 47 is in the closed state, the body ECU 65 controls the relay box 160 (lock relay 101 and unlock relay 103) in conjunction with the door lock command or the door unlock command. When the body ECU 65 receives a door lock command while the DC lid 47 is closed (closed state), it turns on the lock relay 101 in addition to the lock relay 100. Specifically, the body ECU 65 sets "lock relay 100 ON and unlock relay 102 OFF" and "lock relay 101 ON and unlock relay 102 OFF" in response to the door lock command. As a result, the door lock device 80 is locked, and the lid lock device 82, the connector lock device 83, and the lid lock device 87 are also locked.

[0066] When the body ECU 65 receives a door unlock command while the DC lid 47 is in the closed state (closed state), it turns on the unlock relay 103 in addition to the unlock relay 102. Specifically, the body ECU 65 sets "lock relay 100 OFF and unlock relay 102 ON" and "lock relay 101 OFF and unlock relay 102 ON" in response to the door unlock command. As a result, the door lock device 80 is unlocked, and the lid lock device 82, the connector lock device 83, and the lid lock device 87 are also unlocked.

[0067] When the DC lid 47 is in the open state, the body ECU 65 does not interlock the control of the relay box 160 with the door lock command. When the body ECU 65 receives a door lock command while the DC lid 47 is in the open state (open state), it sets "lock relay 100 ON and unlock relay 102 OFF" in response to the door lock command, while maintaining "lock relay 101 OFF and unlock relay 103 OFF" until DC charging starts. Then, during the period from the start of DC charging until the completion of DC charging (i.e., during the execution of DC charging), the body ECU 65 sets "lock relay 101 ON and unlock relay 103 OFF". And when the DC charging is completed, the body ECU 65 sets "lock relay 101 OFF and unlock relay 103 ON". As a result, the door lock device 80 is locked in response to the door lock command, and the lid lock device 82, the connector lock device 83, and the lid lock device 87 are locked only during the execution of DC charging. By locking the lid lock device 82, the connector lock device 83, and the lid lock device 87 during the execution of DC charging, it is possible to suppress pranks on the AC lid 42 and the power reception port unit 40 during the execution of DC charging.

[0068] Note that when the transition of the lid lock device 82, the connector lock device 83, and the lid lock device 87 to the locked state or the unlocked state is completed, the body ECU 65 turns off the lock relay 101 and turns off the unlock relay 103 to maintain the locked state position or the unlocked state position of the respective lock pins 82a, 83a, and 87a of the lid lock device 82, the connector lock device 83, and the lid lock device 87.

[0069] <Timing Chart> FIG. 5 is a diagram showing a timing chart of a comparative example. With the above configuration, it is possible to avoid a situation like the comparative example described below. It is assumed that the lock relays and the unlock relays of the door lock device 80, the lid lock device 82, the connector lock device 83, and the lid lock device 87 of the vehicle according to the comparative example are shared. And, the vehicle according to the comparative example controls the lock relay and the unlock relay in response to a door lock command and a door unlock command. That is, the vehicle according to the comparative example is controlled so that the door lock device 80 and the lid lock device 82, the connector lock device 83, and the lid lock device 87 are always interlocked.

[0070] Referring to FIG. 5, FIG. 5 describes an operation related to DC charging of the user (charging operation), the state of the lid lock device 87, the open / closed state of the DC lid 47, and the lock image of the DC lid 47.

[0071] First, assume that the vehicle is stopped with the DC lid 47 closed. At time t1, the user opens the DC lid 47. Then, the user connects the connector 320 of the DC charging facility 300 to the DC inlet 46 and performs a door lock operation to lock the boarding door at time t2. Along with this door lock operation, a door lock command is sent from the authentication ECU 70 to the body ECU 65. In response to the door lock command, the body ECU 65 causes not only the door lock device 80 but also the lid lock device 82, the connector lock device 83, and the lid lock device 87 to shift to the locked state. Therefore, the lock pin 87a of the lid lock device 87 advances, and the advanced lock pin 87a prevents the DC lid 47 from being closed.

[0072] At time t3, the user performs a start operation to start DC charging. As a result, the connector lock device of the DC charging facility 300 operates, and the connection between the DC inlet 46 and the connector 320 is locked.

[0073] When the DC charging is completed at time t4, the connection between the DC inlet 46 and the connector 320 becomes unlocked, and the connector 320 is removed from the DC inlet 46.

[0074] At time t5, the user attempts to close the DC lid 47. However, since the lid lock device 87 is in the locked state, the closing operation of the DC lid 47 is blocked by the lock pin 87a, and the user cannot close the DC lid 47. To unlock the lid lock device 87, an operation to unlock the boarding door is required. Requiring a separate operation to close the DC lid 47 impairs the convenience for the user.

[0075] FIG. 6 is a diagram showing the timing chart of the present embodiment. Similar to FIG. 5, FIG. 6 shows the operations (charging operations) related to the user's DC charging, the state of the lid lock device 87, the open / closed state of the DC lid 47, and the lock image of the DC lid 47.

[0076] First, assume that the vehicle 1 is stopped with the DC lid 47 closed. At time t10, the user opens the DC lid 47. Then, the user connects the connector 320 of the DC charging facility 300 to the DC inlet 46 and performs a door lock operation to lock the boarding and alighting doors at time t11. Along with this door lock operation, a door lock command is sent from the collation ECU 70 to the body ECU 65. The body ECU 65 shifts the door lock device 80 to the locked state in response to the door lock command. However, the body ECU 65 leaves the lid lock device 82, the connector lock device 83, and the lid lock device 87 in the unlocked state. That is, the lid lock device 87 does not shift to the locked state by the door lock operation. Therefore, at this stage, the user can close the DC lid 47.

[0077] At time t12, the user performs a start operation to start DC charging. As a result, the body ECU 65 shifts the lid lock device 82, the connector lock device 83, and the lid lock device 87 to the locked state. Also, a connector lock device (not shown) of the DC charging facility 300 operates, and the connection between the DC inlet 46 and the connector 320 becomes locked. During the execution of DC charging, the lid lock device 82 also becomes locked. As a result, it becomes impossible to open the AC lid 42 during the execution of DC charging, so it is possible to suppress pranks on the AC lid 42 and the power reception port unit 40 during the execution of DC charging.

[0078] At time t13, DC charging is completed. Due to the completion of DC charging, a connector lock device (not shown) of the DC charging facility 300 operates, and the connection between the DC inlet 46 and the connector 320 becomes unlocked. Then, the user removes the connector 320 from the DC inlet 46.

[0079] Also, upon completion of DC charging, the body ECU 65 shifts the lid lock device 82, the connector lock device 83, and the lid lock device 87 to the unlocked state. As a result, the user who has removed the connector 320 from the DC inlet 46 can close the DC lid 47 at time t14.

[0080] <Flowchart> FIG. 7 is a flowchart showing an example of the procedure of the process executed in response to a door lock command. The process of this flowchart is started by the body ECU 65 when a door lock command is received from the collation ECU 70. Note that each step (hereinafter, the step is abbreviated as "S") of the flowchart shown in FIG. 7 will be described for the case where it is realized by software processing by the body ECU 65, but a part or all of it may be realized by hardware (electric circuit) fabricated in the body ECU 65.

[0081] In S1, the body ECU 65 determines whether the DC lid 47 is open based on the detection result of the lid switch 86. Note that the body ECU 65 may receive the lid signal K2 via the charging ECU 60 and determine whether the DC lid 47 is open based on the lid signal K2, or based on the open / closed state of the DC lid 47 determined by the charging ECU 60 that has received the lid signal K2 from the lid switch 86. If the body ECU 65 determines that the DC lid 47 is open (YES in S1), the process proceeds to S3. If the body ECU 65 determines that the DC lid 47 is not open (NO in S1), the process proceeds to S13.

[0082] In S3, the body ECU 65 maintains the lock relay 101 and the unlock relay 103 in the OFF state. That is, the body ECU 65 maintains the lid lock device 82, the connector lock device 83, and the lid lock device 87 in the unlocked state. Note that the body ECU 65 responds to a door lock command to turn "the lock relay 100 ON and the unlock relay 102 OFF", locks the door lock device 80, and locks the boarding / alighting door.

[0083] In S5, the body ECU 65 determines whether DC charging has started. Whether DC charging has started is transmitted from the charging ECU 60 to the body ECU 65. For example, when a charging start button provided in the DC charging facility 300 is pressed by the user, communication is established between the DC charging facility 300 and the charging ECU 60. When the establishment of this communication is transmitted from the charging ECU 60 to the body ECU 65, the body ECU 65 may detect the start of DC charging. If the body ECU 65 determines that DC charging has not started (NO in S5), it waits for DC charging to start. Until DC charging starts, the user can also close the DC lid 47. If the body ECU 65 determines that DC charging has started (YES in S5), the process proceeds to S7.

[0084] In S7, the body ECU 65 turns "the lock relay 101 ON and the unlock relay 103 OFF" to lock the lid lock device 82, the connector lock device 83, and the lid lock device 87. As a result, during the execution of DC charging, the lid lock device 82 of the AC lid 42 is also in the locked state, so the AC lid 42 cannot be opened. Therefore, it is possible to suppress pranks on the AC lid 42 and the power receiving port unit 40 during the execution of DC charging.

[0085] In S9, the body ECU 65 determines whether the DC charging has been completed. The DC charging ends when the condition is satisfied. As the condition, for example, at least any one of the following may be adopted: the power storage device 10 has been fully charged, the SOC (State Of Charge) of the power storage device 10 has reached the set SOC, the set charging time has elapsed, and the charging end button provided on the DC charging facility 300 has been pressed. The body ECU 65 waits for the DC charging to be completed (NO in S9). When the DC charging is completed (YES in S9), the body ECU 65 proceeds with the process to S11.

[0086] In S11, the body ECU 65 turns the "lock relay 101 OFF and the unlock relay 103 ON" to put the lid lock device 82, the connector lock device 83, and the lid lock device 87 in the unlocked state. Thereby, the user can remove the connector 320 from the DC inlet 46 and close the DC lid 47.

[0087] In S13, the body ECU 65 turns the "lock relay 101 ON and the unlock relay 103 OFF" to put the lid lock device 82, the connector lock device 83, and the lid lock device 87 in the locked state. It is assumed that the DC charging is not executed when the DC lid 47 is not open. Therefore, the body ECU 65 puts the lid lock device 82, the connector lock device 83, and the lid lock device 87 in the locked state in conjunction with the door lock command. Note that the body ECU 65 turns the "lock relay 100 ON and the unlock relay 102 OFF" to also put the door lock device 80 in the locked state in response to the door lock command.

[0088] In S15, the body ECU 65 determines whether it has received an unlock command from the collation ECU 70. If the body ECU 65 determines that it has not received an unlock command (NO in S15), it waits to receive the unlock command. If the body ECU 65 determines that it has received an unlock command (YES in S15), it proceeds with the process to S17.

[0089] In S17, the body ECU 65 turns off the lock relay 101 and turns on the unlock relay 103 to unlock the lid lock device 82, the connector lock device 83, and the lid lock device 87. In addition, in response to the door unlock command, the body ECU 65 turns off the lock relay 100 and turns on the unlock relay 102 to also unlock the door lock device 80.

[0090] As described above, in the vehicle 1 according to the present embodiment, when the DC lid 47 is in the closed state, the control of the relay box 160 (lock relay 101 and unlock relay 103) is interlocked with the door lock command, while when the DC lid 47 is in the open state, the control of the relay box 160 (lock relay 101 and unlock relay 103) is not interlocked with the door lock command. When the DC lid 47 is in the closed state, it is assumed that DC charging is not executed. In this case, by shifting the door lock device 80, the lid lock device 82, the connector lock device 83, and the lid lock device 87 to the locked state all at once in response to the door lock operation, the convenience for the user can be improved.

[0091] On the other hand, when the DC lid 47 is in the open state, it is assumed that DC charging is executed. In this case, if the control of the relay box 160 is linked to the door lock command, after the completion of DC charging, a separate operation (operation for unlocking the boarding and alighting door) is required to close the DC lid 47, which will reduce the convenience for the user. Therefore, by not linking the control of the relay box 160 to the door lock command, it is possible to suppress the reduction of the user's convenience.

[0092] In the vehicle 1 according to the present embodiment, when the DC lid 47 is in the open state, the lid lock device 87 is unlocked until the start of DC charging, the lid lock device 87 is locked during the execution of DC charging, and the lid lock device 87 is unlocked when the DC charging is completed. When the DC charging is completed, the lid lock device 87 is in the unlocked state, so the user can close the DC lid 47 without a separate operation.

[0093] Also, during the execution of DC charging, the lid lock device 82 is also locked. That is, during the execution of DC charging, the AC lid 42 cannot be opened, so it is possible to suppress pranks on the AC lid 42 and the power receiving port unit 40 during the execution of DC charging.

[0094] Also, in the vehicle 1 according to the present embodiment, the relays for switching the supply and cut-off of the operating power to each of the lid lock device 82, the connector lock device 83, and the lid lock device 87 are shared. Therefore, it is not necessary to separately provide a relay for switching the supply and cut-off of the operating power to each of the lid lock device 82, the connector lock device 83, and the lid lock device 87, so the circuit can be configured at low cost.

[0095] [Modification Example] In the embodiment, an example in which each of the lid lock device 82, the connector lock device 83, and the lid lock device 87 includes a lock pin and a drive device as its mechanism has been described. However, the mechanism of each of the lid lock device 82, the connector lock device 83, and the lid lock device 87 is not limited to the above. Various known mechanisms can be adopted for each of the lid lock device 82, the connector lock device 83, and the lid lock device 87.

[0096] The disclosed embodiment should be considered as illustrative in all respects and not restrictive. The scope of the present disclosure is indicated by the claims rather than the description of the above-described embodiment, and is intended to include all modifications within the meaning and scope equivalent to the claims.
